Two static functions are only used if CONFIG_PCI is defined,so only build them
if this is the case. Fixes the build warnings:
arch/x86/kernel/early_printk.c:98:13: warning: ‘mem32_serial_out’ defined but
not used [-Wunused-function]
static void mem32_serial_out(unsigned long addr, int offset, int value)
^
arch/x86/kernel/early_printk.c:105:21: warning: ‘mem32_serial_in’ defined but
not used [-Wunused-function]
static unsigned int mem32_serial_in(unsigned long addr, int offset)
^
Also convert a few related instances of uintXX_t to kernel specific uXX defines.

v2 - Move code to another #ifdef instead of creating a new ifdef pair after
comment by Borislav Petkov <b...@alien8.de>.
v3 - Fixed commit errors from v2, changed some uintXX_t data types to
equivalent uXX.
